IMPROVEMENT IN CHURNS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it 'may concern:

Be it known that I, A. H. MClVAINE, ofsllickslnnny borough, in the county of Luzerne, and State of Pennsylvania, have invented a new and uset'nl Improvement in Churns, of which the following is a specilic-ation.

Nature mul Objects of the-Invention.

My invention consists in the combination of two dashers-one constructed of tlured paddles, framed, horizontally, into a perpemlicular wooden cylinder; the other, consisting of four perpendicular ared paddles, framed, at `the bottom, into two wooden arms, which cross each other at right angles, and fastened,-

at the top, by arms radiating at right angles from a Apipe and cog-wheel, as will be moreinlly explamed; the object of the invention being to facilitate theoperation of 'extracting butter from cream, and to prevent the cream from frothing up and running over at the top ot' the churn during the opera-tion.

General Description.

a isihe body of a cylindrical churn. b are stares, which extend above the churn a, and' support thev beam c, to which is fastened the iron plate Ad.

Theshaft e, provided with the small cog f, is thrust through the holes -in the iron plate 1d, the-beam c, and the small. cog and pipe g, and fastened or screwed into the wooden cylinder h. i

c' is a pivot, which passes through the arms k ofthe outer dasher, intothe bottom of the cylinder h.

The head of the pivot rests in a metal pit, j, in 'the bottom centre ot' the churn a.

The small cog and pipe g, and the armsJf, are Acast in one piece.

The ends of the arms l are fastened in the upper ends ot' the perpendicular flared paddles m, and the arms k are fastened to the lower ends of thesamc.

o are flared paddles, framed intp the cylinder of wood h.. I a

The dared paddles o and the cylinder h compose the inner dasher A.

The small cog and pipe g, and arms l and k, and perpendicular flared paddles m, compose the outer` dasher B.

Motion is communicated to the dashers A and B by the side-cogdriving-wheel CT which vmeshes into the small cogs j' and g.

p. is the axle, upon which the driving-wheel C revolves. n v g isa burr, which holds the driving-wheel upon the axle p.

- r is the handle by which 'power is applied to the driving-wheel.

s is a groove in the outside of the rim of the drivingwheel.

` A cord may be introduced into the groove s, and power attached thereto.

u is a pin, which holds the beam c in place while the churn is being operated.

:e is the lid to the churn.

Operation of the Invention. By placing the dashers A and B intheir proper position, and securing the beam c to the upright staves Q by inserting the pin u in its place, pouring the cream into the churn, and placing the lid :I: upon it, itis ready to be operated. The lid is made in .two equal pieces, and slides on upon the oppositey sides ot' 'the stave's b and shaft e. By turning the driving-,wheel G, which is connected with the small cogs f and g, to the right, the cog f,ito which the inner dasbe-r A is attarhed,.is revolved to the left; consequently the inner dasher A is revolved to the left. The rim of the drivingwheel C passes to the right at the top, or cog f, and'passes to the left at the bottom, or cog g. By passing to the lett, it turns the cog gto the right; consequently, thev outer dasher which is attached to cog g, is turnedto the right. The flared paddles m of the outer dasher B press the cream toward the centre. The llared paddles o ofthe inner dasher A press the cream toward the bottom of 4the churn a, and, in this manner, the cream is prevented tionrfrothing up .and running over the top of the churn. The feat-her edge ofthe paddles` o are under;

the feather or thin edge of the paddles m are placed' toward the centre of the churn. The butter is gathered by a slow, reverse motion of the, dashers. ABy

removing the burr q, the driving-wheel C may be taken otf and laid aside.- Take the lid a: off, removethe pin u', and the beam c, and the dasheis A andl B may be taken out, and thehurn cleaned.

I claim, as my invention- The revolving dashers A and B, when constructed ot' the flared paddles o and m, and fastened to the churn-body a by the staves b and beam e, and operated by the driving-wheel C, and cogs f and g, in the manner and for the purpose speciiied.
